CONTRACT DRYING

Freeze-drying (lyophilistation) is a process where frozen raw materials are placed in a refrigerated vacuum and ice crystals in the product are sublimated into water vapour, while the cell structure of the original product remains.

Although freeze-dried fruits are small and light-weight, studies show that the antioxidant phytochemicals found in the fruits' fresh state are retained at levels almost as high after freeze-drying.
